SPOKE-THROATING MACHINE.

SPECIFICATION formingpart'of Letters Patent No. 230,983, dated August10, 1 880.

Application filed April 24, 1880. (No model.)

To all whom it may concern:

Be it known that I, OSCAR ALLEN, of Mount Morris, in the county ofLivingston, and in the State of New York, have invented certain new anduseful Improvements in Spoke-Throating Machines; and I do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangementof a spokethroating machine, as will be hereinafter more fully setforth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, 1 will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in which-Figure 1 is a front elevation of my machine. Fig. 2 is a plan view of apart thereof. Fig. 3 is a detailed view of a part thereof.

A A represent two frames, each carrying a shaft, 13, having a pulley, 0,near one end for the passage of a belt for rotating the shaft. At ornear the other end of the shaft B is secured the head D, which carriesthe curved adjustable knives or blades F F, for cutting or shaping thethroat of the spoke. At this end of each frame is the form G, as shown.Each frame is pivoted at c to an arm or casting, H, which is adjustablyattached to an upright, I.

The spokes are to be moved forward by machinery or hand with a straightor circular feed carried on a carriage of any suitable description, andheld by the tenon and body of the spoke being passed between the forms GG, one cutter passing over and the other under the spokes, the framescarrying the cutters turning upon the pins or bolts to. The arms H, thathold said bolts or pins, are crooked or built outside of the circle ofthe knives, and the frames may be made to swing from any point from thecutting-edge of the knife to the shaft or spindle. As shown, they aremade to swing nearly horizontally, with the heel of the knife in linewith the pin or bolt, making the shoulder of the spoke straight,

while the front end of the knife moves over or under the body and makesthe same of the same shape as the forms,which may be changed to anyshape desired.

The two oscillating frames are set on a twist, or one ahead of theother, so that the points of the cutters will pass each other. The underframe will hang in right position without any weight or spring, but theupper frame will be held in place by a ball, J, or by a spring. Byraising or lowering the upper frame to give it more or less pitch thespokes may be made thinner or thicker on the face and back, as desired.

On each casting H is mounted a roller, (1, against which the back sideof the frame A works to relieve the friction caused by the belts pullingthe frames A against the castings, and which may run to any angleparallel with the spindles.

The forms G are slotted and adjustable so as to move backward orforward, making the spoke thin in front with thick back and both sidesalike, or in any other shape desired.

The pivot a for each frame being carried outside of the circle, and lowenough to keep the heel of the knife from swinging or moving up or down,makes the shoulder straight or rounding by changing the shape of theknife. The object of this is to throat both sides at once and across thegrain.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The arms H, adjustably and angularly secured to the upright I, andprovided with the studs a and rollers d, in combination with theoscillating frames A, pivoted on said studs and carrying the rotatingknives F, forms Gr, and pulleys O, substantially as described, and forthe purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 22d day of April, 1880.
